warning FORD F-550 2018 Workshop Manual

Transmission Fluid Temperature
Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator will be in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grill. Also,
higher than normal operating temperature
can be caused by special operation
conditions (i.e. snowplowing, towing or
off-road use). Operating the transmission
for extended periods with the gauge in the
higher than normal area may cause
internal transmission damage. You need
to alter the severity of your driving
conditions to lower the transmission
temperature into the normal range. If the
gauge continues to show high
temperatures, see an authorized dealer.
Turbo Boost Gauge (If Equipped)
Indicates the amount of manifold air
pressure in the engine.
DEF Gauge
(If Equipped)
Indicates the current DEF level.
WARNING LAMPS AND
INDICATORS
The following warning lamps and
indicators alert you to a vehicle condition
that may become serious. Some lamps
illuminate when you start your vehicle to
make sure they work. If any lamps remain
on after starting your vehicle, refer to the
respective system warning lamp for further
information. Note:
Some warning indicators appear in
the information display and operate the
same as a warning lamp but do not
illuminate when you start your vehicle.
Adaptive Cruise Control
(If Equipped) The speed control system
indicator light changes color to
indicate what mode the system
is in. See Using Adaptive Cruise Control

adjustment is part of normal system
operation.
Adaptive Steering Off (yellow, solid): The
adaptive steering system is off. It is
possible that the steering wheel may not
be straight when the vehicle is driving
straight ahead. If this message persists,
see an authorized dealer.

Water In Fuel
(If Equipped) WARNING
Do not drain the water-in-fuel
separator while the engine is running.
Failure to follow this warning may
result in fire, serious injury, death or
property damage. During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator lights when
the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See
Fuel Quality (page 187).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.
Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.
